It may be unrelated but I don't know how to proceed in any case to diag the issue.
I have successfully replaced the shifter spring kit as per SVC-09-009 bulletin, as shown in
The bike had gone down on the left side and the shifter spring had been broken. It ran fine after going down, but wouldn't shift up. That's fixed but now it wont start.
Everything went smoothly, although it took about 5 weeks in total between when the cycle was last running and now reassembled - had to wait for flywheel holder tool to come in from UK.
Confirmed shifter works with cover off, reassembled as per video and manual, torqued everything properly along the way. Fresh oil and coolant. Go to start the cycle and it did not start. Cranks okay.
Put battery on the charger for several hours, then used 100amp jump start setting of charger to attempt to start - still no start up. Confirmed we have spark from horizontal cylinder at least. That plug was wet with just a touch of fuel so I assume we have fuel delivery also - pump prime noise is fine too. No swirl in the tank as some have mentioned for disconnected fuel hose.
I have the right side intake snorkel off in order to fascilitate a top-off of the coolant once the cycle is indeed running. This allowed me to spritz some starting fluid into the right side air filter while cranking - still no start.
Bought a brand new AGM battery, put on the charger, then installed on clean terminal connections. At first start attempt we had what sounded like a half cough from one of the cylinders, back to nothing, even with engine start charger added.
How do I determine if I have screwed something up during the shifter repair, or if it's something else from sitting? Fuel filter? I dread the 3+ hours of going back into the alternator cover, redoing coolant and oil, re-sealing the cover with gasket maker etc. unless it's totally necessary.
Here's a video of the bike cranking with the new battery installed. It doesn't sound totally correct to my ears, but I don't know what this machine ought to sound like while cranking; I'm fixing someones bike and am not very familiar.
